XTZ (Tezos)

Tezos aims to offer a more sophisticated infrastructure - meaning that it can expand and improve over time without ever the danger of difficulties. This is something Bitcoin and Ethereum have suffered since they were created. The person holding XTZ can vote on a proposal for a protocol upgrade that has been put forward by developer Tezos. This open source platform bills itself as "secure, upgradeable, and built to last" - and says its smart contract language provides the accuracy needed for high-value use cases. According to Tezos, his approach means that it is futureproof and will "stay up to date in the future," meaning it can embrace the development of blockchain technology. The technology that underpins Tezos was first proposed in a white paper released in September 2014. After a series of delays, the Tezos mainnet was launched four years later.
